Devin for Model Number LG TROMM Dryer DLG8388NM Are both valves equal? I found contradicting documentation in the service manual on which is valve 1 & valve 2. It says valve 1 is supposed to open and remain open while valve 2 is only supposed to open after ignition. We have a complaint that you smell gas when it starts up outside where the dryer vents to. It might just be designed this way because valve 1 opens with the fan running before the igniter is lit. I've tried swapping the wires to the 2 valves, and it seems to work exactly the same, which is surprising. So do both valves work independently and deliver the same amount? Are there specs for the valves somewhere?
Answer Devin, The gas valve is a two-stage valve. When the ignition sequence begins, the igniter is turned on and valve one opens. When the igniter reaches 370°F (188°C), the igniter is turned off and valve two is opened. If the flame detector does not detect ignition, valve two is closed and the process is restarted. If ignition occurs as planned, the drying cycle will operate. It is possible you may have a weak igniter and no ignition on the first or second try. That would explain the gas smell outside.
